Class 10 Our Environment ke “Trophic Levels” ko 30 seconds me samjho: producers (plants), primary–tertiary consumers, apex predators aur decomposers with quick examples for exam recall .

Energy transfer ka 10% rule yaad rakho—har level par 90% energy loss hota hai, isi wajah se food chains generally 4–5 levels tak hi hoti hain.

Perfect for CBSE/Bihar Board style revision—like, share aur save for PYQ-focused prep
